This is a family of pure isofrequency repeaters and isofrequency/frequency changers for DVB-T (Digital Terrestrial Television) with output power up to 1 W, with the option of including an adaptive echo canceller, which is operational even with signal-to-echo ratios of -20 dB measured at the input.
These repeaters operate with input signals as weak as -65 dBm, exhibiting an output MER at nominal power of 33 dB for all UHF broadcast channels (21 to 69) in the absence of echoes. With an input of -80 dBm, the output MER exceeds 21 dB. The echo canceller's performance has been tested and is comparable to that of leading brands on the market.
The COVERTEL Gap-Filler range is characterized by its excellent figures of merit, which contribute to the quality of reception offered to television viewers.
Wish expects to offer low-power DVB-T transmitters in its product range by the end of 2009, complementing its existing product line that addresses all related issues. Wish Soluciones will be exhibiting at Broadcast 2009, Hall 9, Stand 9G02A, where it will present, among other products, the COVERTEL DVB-T Gap Filler range.
